Walter, Chicago,- 111., assignor to' Industrial Patents Corporation, Chicago, 111., 'a 1 corporation of Delaware Application "June 5,1936, sem No. 83.645 i 11 Claims. (01. 101-340) This invention relates to an inking device.

One of the objects of the invention is toflpro-j vide means for uniformly introducing a supplementary fluid into the ink supply of a printing press. I

'Another object of the invention isto provide means for. continuously introducing a volatile fluidinto the ink supply of a printing press for mixture therewith during the. printing operation.

Another object of the invention is to provide means for continuously and uniformly incorporating a highly volatile fluid in the ink supplyv of a printing press duringv theprinting operationto assure maximum strength of the volatile l5 fluid in the "ink, at the time of printing. e 7

'Another object of the invention is to provide means formaintaining volatile ingredients of' an.

ink mixture at full strength throughout the printing operation. Another object of the invention is to provide a printing press having means for continuously tissue. "Also, fdue'to the fact that these casings are'wetted during, stufllng and processing, it is extremely difficult'to cause ink to adhere to the casing surface.

In" my copending application, Serial No.23,669, flledMay 27, 1935, now Patent No. 2,054,148. Sept. 15,: 1936, 1|. have described a method. for direct printing on animal casings which are given no 40 treatment othenthan that normally accorded animal casings, printing directly upon the surface of the casing with an ink containing a protein precipitant such as formaldehyde. r Formaldehyde is highly volatile and due to the large'area of the inking plate of the conventional printing press, will evaporate in large measure before the ink is consumed in the'normal printing operation. Without'the addition of afurther formaldehyde solution to the mass,'it is found that the inking plate must be periodically wiped clean and a fresh ink supply added to the press at short intervals to assure a satisfactory formaldehyde concentration in the ink.

In accordance with the present invention, a supply of ink containing an aldehyde solution is spread upon the inking plate of the printing press. Thereafter andv during .jthe printing operation, a fresh aldehyde solution isj continuously fed drop byv drop" to the lnksupply onthe said inking plate to compensate for thealdeh'yde solutionnormally passing from the ink mass by evaporation. v: The added solution is thoroughly admixed with the ink mass by relative movements of the inking'rol lers in contact 'withthe' inking plate. It will,'therefore, be seenthat the'pr'esent tile ingredients of full strength throughou p i ti o era n. o

Figure '2 [is [a perspective view offa printing:

press utilizing the device of the present invention. fIn'the drawing, l 'designa tes a conventional press having a 'rotary'inking' plate 2 an'dinking rollers 3, 4 and 5, adapted as a group to move with the inked surface s of plate 2 and the sur-j face of the printing type mounted-in'the press. Plate 2 is rigidly secured to s'haftil at 8, which shaft 1 passes through bearing 9 into housing l0. Rotary motion is translated to plate Z'through 25 backwardly and forwardly alternately in contact v g shaft 1 by'suitable drive mechanism in housing It, not shown. "At each cycle of the press,' 'the plate 2*is rotated substantially 909-,"so";;th at at 35.

each cycle" the rollers 3, l and! pass Tover a different portion of the area of plate 2. This,

has the effect of uniformly distributing the ink mass over the entire surface "ofrplate '2 and over. i

the surface of the individual rollers;- J a Rollers 3, 4 and 5 are respectively mounted upon shafts ll, l2,and l3, journalled within v, bearingsfIS and 16, I! and Hi, and'l9 and 20.

Bearings IS, IT and I9, and It," and 20 are respectively connected to swinging arms 2| and, 22, the motion of which iscontrolled by suitable, mechanism mounted within press I. The mechanismfor operating plate '2 and arms-[Hand- 22 are relatively driven, such thatrotary movement is impartedto plate 2 when thelrollers3, 5 are out of contact-therewith. o

l "a d In accordance 'withthe present invention, form aldehyde solution is continuously fed drop 'by drop to the inking surface of plate 2 during the,

printing operation, each'indlvidual drop being thoroughly incorporated with the'ink mass on o 0 invention contemplates an ink'ico'ntaining vola plate 2 through the relative movements of plate glass tube 24,

2 and rollers-3,1 and 5, hereinbefore described. "This is accomplishedthrough the medium of vessel mounted above plate 2 preferably in a manner to direct the individual droplets of the aldehyde solution against printing surface't.

Vessel 23 maybe of any desired material and shape. As: shown in the drawing, it comprises a flanged at its outer surface at25, and having a lowerconical portion .26, provided with drip nozzle 21, controlled by valve 28; Glass tube 24' is-provided with suitable iunit indicia along its longitudinal'surface by whichto'deterl5 mine the volumetric flow of material passing from-tube 24 to plate 2.

Tube 24 is fixedly held above plate z-"py'nang 25in registry with loop 29 rigidly secured to arm 30. Ann 30 is adjustably mounted on stand! 20 ard 3| through the medium of collar, 32 and set a screw 23. Standard 3| is rigidly securedto the framework of press I in a verticalposition, in
